SHOE-SUPPORTING- JACK.

Specification of Letters Patent.

Patented Feb. 2?, 1917.

Application filed April 5, 1915. Serial No. 19,239.

To all whom it may concern:

Be it known that I, MATTHIAS BROOK, a citizen of the United States, residing at Roxbury, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Supporting Jacks; and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in shoe supporting jacks to enable the and arrangements of parts, hereinafter-described and claimed, the advantages of which will be obvious'to those skilled in the art from the following description.

In the accompanying drawings illustrating the preferred form of the invention; Figure 1 represents a partial sideeleva'tion of a sole laying machine embodying the im-' proved form of jack; Fig. 2 is a front eleva tion of that portion of the machine shown in Fig. 1; Fig. 3 is a top plan view of the jack adjusted to support a straight shoe; Fig. 4 is a top plan view of the jack adjusted for a crooked shoe; and Fig. 5 is a detail illustrating the construction for permitting a lateral movement of the toe roll.

The jack shown in the illustrated embodiment of the invention is applied to a sole laying machine which comprises a sole pressing pad indicated at 1, oppositely disposed vertical standards 2 and 3, and a crosshead 4 secured to the standards. It is essential with this type of machine that the shoe shall be positioned upon the jack in a predetermined relation to the sole pressing pad, both longitudinally and angularly, as the shape of the shoe varies according to the style of last, which may be straight or crooked, as shown in Figs. 3 and 4. The shoe supporting jack must have provision for adjustment in order to position shoes of different shapes in a predetermined relation to the pressing pad. To this end the present invention contemplates the provision of improved mechanism for adjusting the relative angular positions of the toe and heel posts in order to insure the positionmg of any style of shoe in a predetermined relation to the pressing pad. The shoe supporting jack is provided with a heel post 7 having the usual last pin 8 actuated by a spring 9 and a toe post 10 having a toe roll 11 arranged to engage with the upper of the shoe and roll thereover as the shoe is positioned .upon the jack. 1 The toe and heel posts are relatively movable toward and from one another to accommodate shoes of varying length and during this movement it will be obvious that the toe roll will ride over the shoe without marring or disfiguring the upper. The heel post is slidingly supported in the usual manner upon a ribbed extension 12 formed integral with the crosshead 4. The position of the toe post with relation to the heel post is conveniently varied in a lateral direction by supporting the toe post upon a swinging head 15 comprising a pair of arms 16 and 17 fulcrumed upon the crosshead 4 and arranged to swing in a substantially horizontal plane. The head is conveniently retained in any adjusted position by a set screw 19 which is threaded in a boss 20 formed upon the head and engages with the curved base 21 of an extension 22 forming a part of the crosshead 4. The toe and heel posts are simultaneously adjusted in the usual manner by a hand wheel 24 secured to the upper end of a shaft 25 which is provided with oppositely extending arms '26 and 27 secured to the toe and heel posts respectively, through links 28 and 29. With this construction it will be noted that the relative angular positions of the toe and heel posts may be conveniently adjusted to accommodate either straight or crooked shoes and position these shoes in a predetermined relation to the pressing pad.

Under certain conditions it may be advisable to obtain an independent lateral adjustment of the toe'roll and to this end, as shown clearly in Fig. 1, the toe roll is journaled upon the lower end of a head 27"" which is slidingly supported in dove-tailed lateral ways 28 formed upon the toe post. The toe roll may be oscillated relative to the toe post by forming the upper portion of the head 27 with inclined faces 30, as shown clearly in Fig. 5, to permit a slight swiveling movement of the toe roll relative to the post. The head 27 may be retained in any adjusted position relative to the toe post 10, so desired, by a retaining member 31 threaded in the toe post and conveniently actuated by an arm 32.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified Without departing from the broader features of the invention.

The invention having been described, What is claimed is 1. A shoe supporting jack, comprising a crosshead, extensions projecting from opposite sides of the crosshead, cooperating heel and toe posts, one of the posts being slidingly supported upon one of the extensions, a head fulcrumed upon the crosshead and carrying the cooperating post, and operative connections for locking the head to the second extension.

2. A shoe supporting jack, comprising a tension projecting trom the crosshead and having a face curved to approximate the path or movement of the toe post when adjusted laterally, and means arranged to engage With the curved face of the extension to retain the head against movement relative thereto.

A shoe supporting jack comprising a crosshead, an extension formed upon the crosshcad, a heel post slidingly supported upon the extension, a head fulcrumed upon the crosshead, a toe post slidingly supported upon the head, and mechanism for relatively adjusting the toe and heel posts.

4t. A shoe supporting jack, comprising a crosshead, extensions projecting from opposite sides of the crosshead, a heel post slidingly supported upon one extension, a head fulcrumed upon the crosshead, a toe post slidingly supported upon the head, and a retaining member threaded in the head and arranged to engage With the second extension to retain the head against movement relative to theextension.
